Now, it's no great secret that the efforts of one Quira, Blade Transform are linked in some way to the Black Garden, however if you haven't heard of it yet here's some evidence from the Grimoire [quote]Quria captured some worm larvae and began experimenting with them. Soon Quria, Blade Transform [b] manifested religious tactics.[/b] By directing worship at the worms, Quria learned it could alter reality with [b] mild ontopathogenic effects. [/b] Being an efficient machine, Quria manufactured a priesthood and ordered all its subminds to believe in worship.[/quote] -Verse 4:9 — open your eye : go into it [quote]how can machines have a god? ...The Vex, for all their voracious intelligence, could not understand or decipher what they found. They searched through all available reactions, and they settled on the [b] course with the greatest payoff...to worship this power, [/b] and to remake themselves in its image. [/quote] -Ikora Rey / Sol progeny [quote]At last, the Heart of the Garden has been destroyed, its stranglehold on the Traveler released. Our Light brightens. But the power of the Vex is not broken. [b] Look into the Vault, Guardian, for it is said to hold powers the Progeny were meant to bring forth [/b] [/quote] - The Speaker / The Black Garden [quote]Deep in the Vault of Glass, the fabric of reality bends to the will of the Vex. Warlocks speak in tones of awe of the Gorgons - creatures that seem to possess a dreaded, almost unimaginable strength:[b] an ontological weapon. [/b] [/quote] - Gorgon My theory, is that due to the Vex's time-traveling nature these events might be closely linked in a causal loop across space and time, this is because from what we've been presented Quira should have been able to gain far more power from Worshiping the 'Deep' (The Hive's word for the Darkness) though the entire Collective Network of the Vex, using Sword Logic on every planet they have conquered to rival that of the hive "Imagine, the machine worlds of the Vex surging with Taken Power, this must not be guardian" Ikoa Rey / Dialouge from the mission 'Paradox' For the Vex, cause does not necessarily have to follow effect, therefore the Black Garden is not necessarily a result of Quria's findings but an aspect of them, the engine in which the Vex Mind learned of the powers of Worshiping the deep. If this is correct, then it greatly increases the impact of Guardians actions in the Black Garden / Vault of Glass, by breaking the patterns of the Vex's Causal loop they may have inadvertently sabotaged Quira's struggles against the hive, now would a completed Black Garden have allowed Quira to manifest the Power to defeat Oryx? Gorgons against Deathsingers? It is unlikely due to Oryx's overwhelming strength as The Taken King, but it does bear thought, especially as the Stranger was so concerned about it's potential.
